If
is the transformed function, then the parent function
has been shifted up vertically by 4 units and horizontally right by 2 units
Step-by-step explanation:
Assume the function is
is the parent function.
A vertical shift,b units up will transform the function to
.
A horizontal shift
units.

For instance, if
, b=4, and a=2 units.
Then the transformed function becomes:

Option D.
Step-by-step explanation:
The formula for total debt ratio is

It can be rewritten as
.... (1)
We know that,
... (2)
Using (1) and (2) we get

Substitute total debt ratio=0.46 in the above equation.






Therefore, the correct option is D.
Answer:
60 minutes
Step-by-step explanation:
Let the number of minutes be represented as x
For Plan A
Plan A charges $35 plus $0.25 per minute for calls.
$35 + $0.25 × x
35 + 0.25x
For Plan B
Plan B charges $20 plus $0.50 per minute for calls.
$20 + $0.50 × x
20 + 0.50x
For what number of minutes do both plans cost the same amount?
This is calculated by equating Plan A to Plan B
Plan A = Plan B
35 + 0.25x = 20 + 0.50x
Collect like terms
35 - 20 = 0.50x - 0.25x
15 = 0.25x
x = 15/0.25
x = 60 minutes.
Hence, the number of minutes that both plans cost the same amount is 60 minutes
